A family friend of Paula Broadwell, the author who carried on an affair with former CIA Director David Petraeus, tells ABC News that Broadwell “deeply regrets the damage that’s been done to her family” from the dalliance.

The person close to Broadwell also told ABC News Sunday night, that Broadwell is devastated by the fallout, which led to Petraeus’ resignation from the CIA. The friend spoke on condition of anonymity because he was not authorized to speak publicly.

Broadwell, her husband, Scott, and their two young sons, drove back to their home in Charlotte, N.C., Sunday, according to the friend. The family was greeted by more than 25 supportive friends and neighbors upon their arrival.

Broadwell didn’t react to reporters gathered outside the home, but her husband said “no comment at this time” and a possible statement would be coming soon, according to ABC News affiliate WSOC.

Broadwell left again this afternoon without speaking to reporters.

The 40-year-old author, who wrote the biography on Gen. Petraeus, “All In,” spent more than a week at her brother’s Washington, D.C., home after news broke of the affair. The friend says Broadwell is now trying to “focus on her family.”
